JOSEPH M. SHIVELY, OF ALFRED, KANSAS, ASSIGNOR T O DEERING HARVESTERCOMPANY,

CORN-SHOGKER.

SPECIFICATION forming part of Letters Patent No. 681,517, dated. August27, 1901.

Application filed February 6, 1901. Serial No. 46,321. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH M. SHIVELY, a citizen of the UnitedStates,residing at Alfred, in the county of Douglas and State of Kansas,have invented certain new and useful Improvements in Corn-Shockers; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, forming a part of this specification.

My invention relates to devices for lifting the shock formed upon themachine and depositing it upon the ground. It is an improvement upon themachine patented to me May 5, 1896, No. 559,754; and it consists inmeans for rendering the shock-lifting core semi-automatic in its actionin dropping the shock.

In the drawings, Figure l is a perspective view of the core around whichthe shock is formed, its radial arms and spreaders, and means foroperating them, all as in position while sustaining the shock whenforming there around. Fig. 2 shows the same parts, but with thespreaders and radial arms closed to the position they occupy when beingdrawn from the shock. Fig. 3 is a plan view of the tripping-latch. Fig.4. is a side elevation of the parts shown in Fig. 3. Fig. 5 is alongitudinal sectional view of the devices for holding the radialprojecting arms in position. Fig. 6 is a plan View of parts shown inFig. 5. Fig. 7 is a side elevation of the means provided for locking thetelescoping pipes together during withdrawal of the core from the shock.Fig. Sis a side elevation of parts shown in Fig. 7 with one of the barsit removed, but which has been turned through an angle of ninety degreesabout a vertical axis; and Fig. 9 is a perspective view of a portion ofthe revolving table,showing the square stud which supports theshock-forming post in its vertical positionand causes the same torevolve.

to, at its center I secure to the rotary table the square stud b, whichfits within the lower end of the square pipe A.

C is a square pipe outside the square pipe When the ropes are drawn, bymeans of Windlass or otherwise, the movement of the pipe A, having thedisk Ct through the pipe 0, causes the disk at to press the spreadersoutward. It is preferable that they be moved substantially equally, andhence I provide the chains a and link them together.

So far as now described this construction is found in the patent abovereferred to and need not be dwelt upon.

Upon the pipe C is clamped the sleeve F. It is constructed as shown inFigs. 5 and 6, its size being such as to pass freely onto the pipe C,but by means of the pinch-bolt f may be secured to the pipe at anydesired place. This is for varying the vertical position of the arms toconform them to corn of dilferent heights.

f,- f f and f are arms pivoted to the sleeve F at f Each arm isprovided'with an upturned end f near its pivot, as shown in Fig. 5.

Adapted to slide freely for a limited distance on the sleeve F is thecollar G, having the downwardly-projecting peripheral flange 1 and H,and extending upwardly outside of a the pipe C are the bars h and h, andconnecting the said bars at the top is the plate It.

Upon the two bars are the stops 7?? and h Surrounding the pipe 0 and theparts last described is the ring I, and extending upwardly from it isthe bar I, having the notches i, 2', t

and i This bar is sustained at its upper end by mechanism soon to bedescribed.

Extending from the case of the pulley d is a slotted link 61 In orderthat the core of my shocking-machine may rotate while the shock isaccumulating without twisting the ropes 61 the swivel a, beforementioned, is provided, and in order that the core may rotate withoutcarrying the bar I with itthe said core is free to turn in the ring I.Upon the top of the crane-arm -D is the latch for the bar I. This partis shown in detail in Figs. 3 and i. A slotted sleeve K is pivoted atand 70' between the arms 70 and 70 which arms are formed by bending thepart as shown in Fig. 3. The part last mentioned is riveted to the upperend of the crane D. Within this slotted sleeve is pivoted the latch L,which is adapted to engage any of the notches z', 7}, 1' or t of the barI. As the shock when suspended and being moved from the shocking-tableis likely to swing from side to side, the sleeve K is pivoted, as beforestated, and in order that the bar I may not crampwithin the slot in thesleeve the slot is made sufficiently long to permit of considerablevibration. The upper portion of the crane D is constructed of bars ofiron D preferably formed,as shown in Fig. 1, to give place forsecurement of the end of the rope. This forms a support for the pulley dand place for attaching the locking device that engages the bar I. Thespring-latch L, pivoted within the sleeve K, has secured to it the ropeZ, which leads downward along the arm D to within convenient reach ofthe operator.

The operation of my device is as follows: With the arms f, f f and fraised, as shown in Fig. 1, and the shock formed, the rope d is pulledby Windlass or otherwise, and as the pipe A, to which the rope isindirectly connected, moves upward the disk a forces the spreaders E tothe position shown. The core and shock surrounding it as a whole is thenlifted to any desired height to draw the pipe A from the square stud b,which projects upward from the rotary shocking-table. The crane is thenswung to such a position that the shock'may be dropped to the groundsufficiently far from the standing corn to permit the machine to passupon another round, as in my patent above referred to. As the shockforming device is raised the bar 1 passes upwardly through the sleeve K,so that one of the notches "i, i, 71 or i is engaged by the latch L.When the shock is to be dropped, the rope d is set free. The Weight ofthe core and the shock surroundingit is then sustained by the bar I, thering I of which comes in contact with the plate It and draws the collarG, through the intermediacy of the bars 71. and the loop H, upwardrelative to the sleeve F,

and thus disengages the arms f, f f and f and permits them to fall. Notonly this, the weight of the entire apparatus being sustained by the barI the pipe A is free to move downward by its weight or by the pressureof the spring e, and thus permit the spreaders E to collapse. The actionof the parts thus far is to permit the shock to be dropped to theground. The core has yet to be drawn upward through the top of theshock. This isdone by pulling upon the rope cl until the core is raisedsufficiently high. It is plain, however, that if the pipe A were free tomove upward relative to the other parts the disk a would force theSpreaders and prevent the withdrawing of the core from the shock. Uponthe pipe 0 is the spring-latch M, with a pin m, adapted to enter thehole m in the pipe A. When the latter pipe is at its lowest position,with the two pipes locked together, it will be seen that the stress isreapplied to the rope C1 The spiders are not moved. The core having beenfully removed from the shock is swung to its position over the shockforming table and lowered. The spring-latch L is disengaged from thenotches t', z", '5 or 11 by pulling upon the rope Z. The pipe A is thenplaced in position on the square stud b of the rotary table and thelatch M is withdrawn, so as to leave the pipes C and A free to moverelatively to each other in the next operation of removing the shock.The arms f, f f and f are raised and the collar G permitted to engagethem and hold them in the position shown.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a corn-shocking machine, the combi-- nation with a shock-formingpost having pivoted arms, a trigger adapted to engage said arms and tolock them in radial posit-ion relative to said post and by longitudinalmovement of same, relative to said post, to unlock said arms, and ashock-lifting hoist, of a trigger pull consisting of the notched bar 1'adapted to engage said trigger, a guide upon the arm of said hoist, saidnotched bar passing upward through said guide, and a catch upon saidguide whereby the notched bar may -be arrested from downward movementwhen the hoisting device is permitted to lower the shock forming post,substantially as described.

2, In a corn-shocking machine, the'combination with a shock-forming posthaving pivoted arms, a trigger adapted to engage said arms and to lockthem in radial position relative to said post and by longitudinalmovement of same, relative to said post, to unlock said arms, and ashock-lifting hoist, of a trigger pull consisting of the notched bar Iadapted to engage said trigger, a guide upon the arm of said hoist, saidnotched bar passing upward through said guide, and a catch upon saidguide whereby the notched bar may be arrested from downward movementwhen the hoisting device is permitted to lower the shock-forming post,means for moving said catch out of engagement with said notched bar topermit the same to move downward when the shock-forming post is loweredto its position on the table, substantially as described.

3. In a corn-shocking machine, the combination with a shock-forming posthaving pivoted arms, a trigger adapted to engage said arms and to lockthem in radial position relative to said post and by longitudinalmovement of same, relative to said post, to unlock said arms, and ashock-lifting device conneoted to the top of said post by a swivel, of acatch on said shock-lifting device and a trigger-pull extending fromsaid catch downward and surrounding said trigger, whereby theshock-forming post is free to rotate while forming the shock withoutafiecting the position of said trigger-pull relative to said liftingdevice, substantially as described.

4. In a corn-shocking machine, the combination with a shock-forming posthaving piv oted arms, a trigger adapted to engage said arms and to lockthem in radial position relative to said post and by longitudinalmovement of same, relative to said post, to unlock said arms, and ashock-lifting device, of a trigger-pull adapted to move a limiteddistance longitudinally relative to said trigger and to engagetherewith, whereby the trigger is permitted to move downward with theshock-forming post for a little distance and the said trigger thenarrested by engagement with the said trigger-pull, whereby the momentumof the descending post and shock is instrumental in setting the armsfree, substantially as described.
